Borneo sword for I.D

[Royston]

This is the first sword I have bought in a while as prices seem to be very high these days ( unless you are selling )
Is this a Langgai Tinggang ?
If not, then what ?
It is large at 57cm long and weighs 0.8kg.
It is a bit crude but I think too good to be tourist.
The face on the antler hilt is an added bonus.

Thanks in advance
Roy
